ATTORNEY than when in thecupper position, the rock shaft 13 beinglocated near the top of the casing. In order to close in the space between the opening .2 and the curtain 17 when in' the lowered position,side wings 19 are provided flanking the opening 2 and extending anappropriate distance into the casing, these wings being wide at thebottom and narrow at the top to conform in general to the position ofthe curtain when extended, and yet not interfering with the raising ofthe curtain by the upward movement of the free ends of the arms 14, thecurtain then folding on itself, as indicated in Fig. 4. .The normaltendency of the platform is towardthe raised position, and this iscaused by a weight 20 which may be made fast to one of the arms 14; inadjustable relation thereto'by means of a set screw 21. Usually a singleweight is ample, but this does not preclude the use of more than oneweight, and the a plieation of the weights to both arms it il such bedesirable, or any other means for im )arting to the platform 7 an 5upwardly ten ency may be employed;

.1 Fast to the platform 7 betweep the ends? thereof and on opposit'sidesof the cer tter' line of the platform are rods 22 which may be maderigid with relation to the platform by nuts 23 applied to each rod aboveand below the platform. Also, made fast to the platform adjacent to butnearer the center line of the platform than are the rods, are sidemembers 24 serving as guides to direct a hen moving along the platformafter entering the casing through the opening 2, toward the other end ofthe platform. Each rod 22 carries a crown sheet 25, these crown sheetsbeing appropriately bent so that the edges remote from the rods overhangthe portion of the platform between the side members 24 in elevatedrelation to the upper surface of the platform and said side members. Thecrown plates ar each supported on a respective rod by spaced brackets26, 27, each provided with a passage for its rod, and a pin 28 intraversing relation to each rod and under-riding the bracket 27 servesto hold tbe'respcctive crown plate in the desired elevated position withrespect to the platform. By providing each rod 22 with a suitable numberof spaced perforations, the pins 28 may be introduced into any desiredones of the perforations to ell'cct the adjustment of the'crown platesto accommodate the device to fowls of ditl'erent heights. The meetingedges of the crown plates are rounded oneaway from the other at their.ends, as indicated at 22), but these meeting edges do not come intoactual contact, being spaced :1 short distance one fron the other, andthere held byqionm-utiup yokcs' 3t), 31, respectively, near the r nd. ofthe crowu platcs and each shaped to support certain mechanism to bedescribed. The

yoke 30 is provided with spaced parallel wings 32 between whichextend'sa pivot pin carrying a prudent arm 34 journaled in the lower endof which a roller 35 which may be of suitable material to carry a.marking ink. The wings 3'2 also carry another pivot pin 36 from whichthcrehangs a hookshaped plate 37. The wings 32 also carry still anotherpin 38, on which is mounted a yoke like spring 39 in the path of thependent arms 3t. so that when these arms with the roller 35 are swungupwardly about the pin 33 in a manner to be described, they willultimately engage the spring 39 and move the same against its normaltendency, this spring when the arms 34 are released tending to move ittoward its ,initial position.

Mounted in the yoke 31 is a roller 40 which may have its peripherycovered with a layer 41 of suitable material, such as paper, capable ofreceiving an imprint. Since it is desirable to remove the roller 40, itis provided with a journal 42, the ends of which are adapted to enterinclined recesses -13 in the legs of the yoke, and the roller is heldagainst accidental displacement by a t1on to hold the journal 42 in therecessed bearings therefor. Underriding the roller 18 a. guard plate 45with one edge in close guard plate curving away from the roller.

lach hen is provided with asaddle structure con'lprising a channelmember 46 of suflicient length with the upper edges 47 returned on themselves. The channel member is received between two wire members 48 inspaced relation one to the other, and at one end these wire members arebent oppositely at an angle to the main portion of the wires, as shownat a9, and then have a return connecting member joining the outer endsof the bent portions, the members 48, 49 and 50 being preferably formedof one piece of wire, although th s does not preclude the formation ofthese structures otherwise. The other ends of the wire members 48 arecoupled together by a connector 5t, and beyond this the wire membersdiverge and then conver e to form grip ing fingers 52 designedtoiambrace the ha y of the fowl adjacent. the junction of the wings ofthe fowl with the body thereof, while thechannel member 46 rests uponthe back of the fowl. The connectors 50 and 51 serve to sup ort theendsot the channel member, \vhi e the wire members 48 grip the channelmember and the return edges 47 terminate in spaced relation to the wiremembers 48, so that the return members 47 may override the crown )ltlteb25 and the wire members 45 may underride these plates at the spacedmeeting edge portions thereof, the several parts being suitablyproportioned for this spring linger 44 hearing thereon in adirecrelation to the roller, and the body of the purpose, and the endsof the inturned edges 47 being suitably rounded as indicated at 53 so asto coact with the rounded ed cs 29 of the crown plates to guide the sadle into a pro er relation to the crown members 25.

hile there may be considerable difference in height between fowls ofdifierent breeds, selected fowls of the same breed are all ofapproximately the-same height, and the crown plates 25 may, therefore,be ad- 'usted in a suitable positlon'and the device eing used with hensof practically all the same height, a hen entering the nest structurethrough the conduit defined by the side 15, members 24 and crown plates25 will bring,

the saddle member into pr'oper relation to the crown plates so that thelatter will engage the saddle member between the downturned edges 47 andthe wires 48,'and these an crown plates will guide the saddle during thesubsequent operations. I

Fastto the arm 55 is a finger '59 havingone end secured to the arm and the other projecting into closilrelationto the imprinting member 57 and there formed with teeth 60."

. If it be assumed that a hen with the saddle attached enters the nestcasing throu h 'the opening 2, the saddle will be broug t into suchrelation to the crown plates 25 as to be enga ed by the spaaced meetingedges thereof an be directed y these edges along said plates, theinitial position of the sad- 45- cated in Fig. 4.

The parts are so proportioned t atultimately the imprintingl member 57 is brought into engagement wit the.inking roller and ,the latter is brought, into engagement with thespring-39 an printing member are pressed together snlfi: ciently tocause .a transfer of inkto t he printing member; At the -same time thearm .55 is given a sufiicientbackward inchnation to cause the tooth 56to escape, from the book 37 and the sp ng 58 impelsthe warm 55 onto theimpression. receiv ng sur.-'

dle with relation to the plates being indi the roller and im- 'of thedisk being suc that thesq face 41 so that an imprint is made thereon.Simultaneously with the imprinting, the toothed finger 59 cnga es thesurface 41 and further movement of the saddle causes a rotative movementof the roller until ultimately the guard plate is reached, and then thearm is moved away from the roller 40, the finger 59 participating inthis movement, and this finger protects the imprinting incmber figv fromengagement with the guard plate. hen the guard plate is passed, thesp1'ii1g 5'8-returns the arm 55 to its initial position within thechannel member 46, an im' rint having in the meantime been produce uponthe surface 41 9f the roller 40.

By having the imprintin members 57 characteristically different hr thedifierent hens, difi'ercnt numerals or letters being sufficient, eachhen on entering the nest structure will cause an imprint Individual tothe hen to be produced upon the surface 41, so that subsequentinspection will show what hens have visited the nest. The narrowness ofthe conduit and the engagement of the saddle with the crown platesprevents the hen from turning back, so that the hen must proceed as faras the nest which, as wlill hereinafter appear, is beyond the crownates.

p In line with the crown plates is a hood 60 formed of side and topmembers and extending away from the crown plates, thishood beingsupported by side strips 61 fast to the sides of the casing andsufiiciently distant' from the end of the casing carrying the frame orwindow 3 to form a nest compartment. Within this compartment there 1slocated a frame 62 at a suitable distance above the bottom of thecasing, and at one edge connected by hinges 63 to theside strips 61.This frame 62 is provided with a central depressed portion or bowl 64constituting the nest for the hen and usually this bowl ma be providedwith some soft lining in teriah Through the bottom of the bowl t ere isprovided a passage 65 designed for the escape of eggs laid in the nest.

VVhei-e the nest is provided with a adding or other soft material,cleansing o the nest should be rendered eas], and or thispurpose thehinges 63 may omitted and the nest framemay then be readily removed whendesired without the necessity. ofusing tools.

.. Erect'ed on the bottom of thecasingbelow the nest compartment-and'toone side of the center of the nest is a post or standa 166, on top ofwhich is pivoted a 6 tovided with a circular series of perforations 68,the relation of the lpost 66 andthe. pivot erforations maybe brought insuccession neath the pasage 65 in the nest bowl. .In orderto a0 receiveand retain eggs passing from the nest bowl, the disk 67 at eachperforation GS is provided witl'ra receptacle 69 of some flexiblematerial which will arrestthe fall of an egg from the ncstbowl withoutinjury to such egg, and at the same time-of suliicient capacity to holdthe egg below the surface of the disk 67. Such receptacle 69 may bemadefast'to the disk 67 or may be removably mounted thereon. About theedge of the disk (37 are teeth 70 which may be made of the material ofthe disk by suitably punching the same. There is provided one tooth 70for each passage 68, so that a suitable impelling l'neans engaging theteeth in succession will cause a step by step rotative movement of thedisk to bring the receptacles (39 in succession into underlying relationto the passage 65 through the bowl 6-1.

In the particularstructure shown in the. drawings, the top of thestandard 6 is .expanded so as to provide a broad bearin and supportingsurface for the disk (37, an this standard receives a pivot pin 71,about which the disk moves, and this 'pivotpin may be a headed pin toconfine to the pivot alever 72 for movement about. the axis of the disk7 on the pin 71, a washer 73 separating the lever from the disk. Thislever is a lever of the first order. The lever is in overlying relationto the disk 67 and at one point in the lon er arm of the lever it isbent away from the disk, as indicated at 74, see Fig. 9, so'that theouter extremity of the arm is more distant from the face of the diskthan the portion of the arm adjacent the pivot of the lever. the raisedportion of the arm ishent' into a return loo 75, through two parallelmembers of w rich are ahned perforations for a dog 7 6 sup orted by aspring 77 fast at the end remote tom the dog to the lever arm; The end75 of the lever arm is so disposed as to override the teeth 70 insuccession, and the dog 76 will move along the disk near the peripherythereof in engagement therewith with the spring 77 under stress, andwhen the dog reaches a tooth 70, which latter is depressed below thesurface of the disk, the spring 77 forces the dog against the tooth sothatthe dog ma y be brought into engagement-with the shoulder in thedisk, formed by the depression of the tooth. Of courseE this structure"is more or less indicative o proper (direction, moved in the othertooth in order, so that other drive mechanisms for the disk, and itis,therefore, to be understood that any rea rocking movement to the lever,th dlfiik will be rotated anappropriate distance in the over the diskinto enga ement with the next a continuation of the rocking movement 0the lever, the disk is rotated step by step. To prevent reverse Theouter end of.

radial arm 93 in 'tion 97 is a sprin spring-detain and when the lever"is direction it will ride idly When the nest frame 62 is depressmovement of the disk (37, there is provided a back stop pawl 78 whichmay be in the form of a simple elastic strip fast at one end. to oneside of the casing, and at the other end formed with a tooth 79 adaptedto the teeth 70 to hold the disk 67 while the reverse movement of thelever 72 is taking place, but yielding to the active movement of saidlever, in which active movement the disk 67 participates.

Mounted on the bottom of the casing 1 is a bearing block 80 for a bellcrank lever 81, to one arm of which there is connected one end of a link82, the other end of which is connected to the short arm of the leyer 72, and on this link is a sto piece 83; The other end of the lever 81 isconnected by a link 81 to a bracket 85 on the under side of the platform7. \Vhenever the Jlatform 7 is depressed, motion is imparted y the link8% to the lever 81, and from thence motion is imparted to the lever 72by the link 82, this motion resultin in the active movementof the lever7 2 to give rotative movement to the disk 77 a distance equal to thespace between the centers of two'adjacent erforations 68. \Vhen theplatform 7 rises, the lever 7 2 is moved backwardly b the link and leverconnection with the plat orm until the dog 76 is 1n engagement with thenext tooth 70in order.

Fast to the under side of the platform 7 is a keeper plate 86, andpivotally supported in a bearin member 87 on the bottom of the casing isa liell crank lever 88 having :1 normally upright arm terminating in atooth 89 adapted to the keeper 86. The other arm of the lever 88 isrovided with a weight 90 tendin to hold tie lever '88 in such positionthat w en the platform 7 is depressed, the hook or latch end 89 willengage the kee r 86.

Mounted in spaced bearings 91 on the bot tom of the casing is a shaft 92having a position to engage under the weight 90 of t clever 88, and thisrock shaft extends to a. point beneath the. nest connected to the freeend of which is a rod or bar 95. having its free end on aging under thatportion of the frame 62 a jacent to the frame 3, the rod 95 being'guidedby a guide glate'tlfi fast to the casing 1. At an mtenneiate "point, theshaft is provided with a lateral '97,i and-enfg'aging this bent per:

98 ast to the citsmfi,

to old the shaft in sue sltion that erod 95 will then be in its highestposition, the arm 94'be'mg properly ated to the shaft 92 for thisegnrpose.

by the weightofahen, such" motion is imparted throughthe rod 95 to theshaft 92 to rock the latter in a direction against the action -of thespring 98,. and thearm 93 is so re e polated to the shaft 92 that theweight 90 will be elevated, and since lever 88 are fast one to the lever'88 will be rocked in carry a tooth 89 away from the keeper 81'. thusreleasing the platform 7 through the action of the weight engaging thekeeper 83 holding the form 7 in the lower position.

Adjacent the lever 88 is another bell crank lever 99 carried by ajournal block 100 fast to the bottom of the casing, and this lever hasone end upturned, as shown at 101, the structure being most clearlyillus trated in Fig. 11. The arm of the lever 99 having the upturned end101 is )rovidcd with a lateral extension 102 uuticrriding other. thesaid a direction to plal the weighted arm of the lever 88 and a spring103 engaging that arm of the lever 99 having the upturned end 101 tendsto normally hold this lever in one position. The other end of the lever99 is COX'HIPCi'Qd to a link 104 extending through a perforation 105 inthe end of the casing having the 0 ening 2, and at the outer end isconnecte to a pivot plate 105 fast to a platform 106 connected to thecorresponding} end of the casing exterior thereto by hinges 107, thisplatform being so related to the opening 2 that a fowl passing into orout of the casing will step upon the platform 106. Mounted on the bottomof the casing by means of journal blocks 108 is a rock shaft 109 havinga crank end 110 in normal. overriding relation to the upturned end 101of the lever 99. The other end of the shaft 109 is provided with aradial arm 111. which may be of sufiicient weight to hold. the shaft 109in position with the crank end 110 overriding, the end. 101 of the lever09. There is, also, provided another rock shaft 112 mounted in journalblocks 113 on the bottom of the casing, and at opposite ends of thisshaft are arms 114 and 115 respectively, these arms being shown as at rght angles one to the other, and in normal position the am 115 lies nearthe bottom of .the casing, while the arm 114 is upright, and the end ofthis arm 114 may be extendechas shown at 116. The arm 115 underrides thearm 111 on the shaft 109, and is in turn overridden by a s ring bar 117made fast at one end to the bottom of the casing, and at the other endprovided with a striker 118 in position to engage a bell 119 mounted onthe bottom of the casing. An ofl'set portion 120 ofthe shaft 112 servesto prevent movement of the shaft beyond a certain distance in onedirection, and, therefore, the arm 115 need not be in actual contactwith the bottom of the casing, but may be engaged by the spring bar 117which i. this weight and the i l l 20, the tooth 851 when p will tend atall times to hold the arm 114 in the upright position, but will yield toa force applied to the-end 116 of the arm 1 114. Fast on the under sideof the disk 07 is a finger 121 in position to engage the end 116 of theman 114 once during each complete rotation of the disk 07. and thedirection oi movement of the finger 121 is such as to cause a rocking ofthe shaft 112 against hraction oi" the spring bar 117, which rockingniovcu'icnttwill art on the arm 111 to rorrrs iondingly rock lhn shaft10!! and rarrv the crank end 110 out oi the path of the upturned cud101. of the lever 00. so that the latter no longer locked. by the crankcud 110 and the lever 99 may thereby be moved under an appropriatelyapplied force. As soon as the finger 121 escapes from the end 116 of thearm 114-, the action of the spring rod 117 will return the shaft 112 toits normal position and the reaction oi the spring rod 117 will carrythe striker 118 in engagement with the bell 119, thus ca using thesounding of said bell When the nest. structure is ready for use, theplatform 7 is in the depressed position in which it is nelrl by theengagementof the hook end 89 ot' the lever 88 with, the keeper 8 L andthe crank end 11.0 of the rock shaft 101i is end 101 of the lever 99.The nest frame 62 is also in the elevated position because of the actionof the spring 98 on the shaft 92. Furthermore the curtain 17 is in theraised position since this the position assumed by the curtain when theplatform 7 is in the lowered position.

Now, let. it he assumed that a hen desiring to lay an egg enters thenest structure through the opening 2. The hen on step-- ping on theoutside platform 106 does not aii'ect this platform, since it is heldagainst movement by the crank 110. The. hen approaches the nestcompartment through the passage defined by {the side members 24, and thecrown plates *25, and the imprinting member in the saddle carried by thehen is caused to operate in the manner already described. so that animpression characteristic of the hen entering the nest is made upon therecord sheet 41, and then the hen proceeds through the hood to the nestcompartment and ultimately steps upon ihtnest, which yields slightlyunder the weighl of the hen, and this yielding causes a rocking of theshaft 02 against the action of the spring 98 to rock the lever 88 to anextent sur'licient to remove the hook 89 from the keeper 86, when theweight 20 becomes active to elevate the platform 7 and lower the curtain17, so that no more hens may enter the nest. structure while beingoccupied by the hen already present. When the egg is laid, it willgravitate from ij'ie'nest through the passage into the receptacle 69then under the passage (35. The hen now passes ut of the nest throughthe hood 60, this being the only way of passage from the nest inoverriding relation to theconmartlnent, and as soon as the weight of thehen acts on the platform 7, the latter is depressed, raising the curtain17 and bring ing the keeper 86 into engagement with the hook cud so ofthe lever 88, thus locking the platform 7 in the depressed 1308111011,and the -rpring 0S acts as soon as the hen leaves the nest t again raisethe nest to the clevatcd position. (in the downward movement of theplatform 7 the disk G'i'is given a rotative movement in the manneralready described to carry the filled receptacle 05) from hcneath theopening 65 and to place. the next receptacle in order under the pas sage(35. The parts remain in this imsition when the hen leaves the nest andthe device is ready for the entrance of another hen. The operationsdescribed are repeated for each hen, and each hen entering the deviceleaves a record 113011 the record sheet 41. characteristic of the)articular hen. Ultimatclythe capacity 0 the device is reached, and whenthe lasthen in order reaches the platform 7 the downward movement ofthis platform causes a rotative movement of the disk 67 which will bringthe finger 121 into engagement with the end 116 of the arm 114, causinga rocking of the shaft 112 in the direction to actuate the shaft 109 soas to move the crank 1.10 out of the path of the upturned end 101 of thelever 99 and to raise the striker 118. The parts are so adjusted that afurther movement of the disk 67 after the last depression of theplatform 7 will carry the finger 1521 past the end 116 of the arm 114,so that the latter is released and the return movement of the striker118 causes the sounding of a signal, but the sounding of the signal onlyoccurs when the poultryman is setting the device for use, and after thealarm sounds the disk 67 is moved backward until it stops, when thefirst pocket 69 in order is beneath the opening 65. The weight on theoutside plat form 106 causes a movement of the lever 90 sufticient tobring the upturned end 101 in such relation to the crank end 110 thatwhen the arm 11.1 is released. the crank end 110 will no longer overridethe upturned end 1.01, but the full movement of the platform 106 isprevented by the spring 103. \Vhen the hen finally emerges through theopening 2 and steps upon the platform 106, the weight of the hen issufficient to overcome the spring 103 and the. lever 09 is furtherrocked to cause the extension 102 undcrriding the lever 88 to move thelatter to an extent sufficient to release the keeper from the hook end89, so that the platform 7 will rise under the action of the weight 20and lower the curtain. The nest structure is, therefore, closed to theentrance of other hens by the locking of the curtain which occurs on thelast hen leaving the nest. st ructure, .so that should the poultrymannot at once attend to the structure to reset it, no

further use of the. structum is permitted because of the lowering of thecurtain.

By comparing the imprints on the record sheet 41 with the eggs in thereceptacles (30, the eggs ma} be identified with the particular henslaying them.

To rest the apparatus. it is only necessary to remove the eggs from thereceptacles 0 and to depress the platform 7, which will cause theraising of the curtain and then by lifting the outside platform 100 thelever 00 will move under the ovcrhalaneing action of the arm having theupturned end 101 which may he augmented hy a. light: spring 122 engagingthe extension 102. sut' liciently to carry the end 101 out of the pathof the crank 110, and the latter will then he moved lrv the rocking ofthe shaft 100 under the (o'er-balancing action of the arm 111 intooverriding relation to the end 101, thus locking the lever 00 andplatform 106 in operative position, the disk 67 having been properly setas before explained.
